Dr. Flores wants to know which of the forum claims is best supported by the evidence you have gathered from your previous Sim observations and the text. Select the claim you think is best
supported from the options below.
Claim 1: Molecules in a substance disappear or no longer exist when a substance changes
phase
Claim 2: Molecules in a substance move differently when a substance changes phase.
Claim 3: Molecules in a substance change into a new kind of molecule during a phase change.

water   molecules stay close to each other through cohesion, the collective action of hydrogen bonds between water molecules. cohesion plants draw water upwards from the root through the stem's transport tubes (xylem) to the leaf. this transport occurs even in large trees and against gravity. transpiration, evaporation of water from plant leaves, creates a tension on water molecules being pulled up from the stem and roots.

water also has high (the attraction of one substance to another) properties because of its polar nature. adhesion of water molecules to plant cell walls counteract gravity while water is transported from roots to leaves.

water exhibits a very high surface tension when compared to other liquids. surface tension is a property of a liquid that holds the surface together and allows it to resist an external force. by capillary action, the water forms concave menisci inside the pores. the high surface tension of water pulls the concavity outwards, generating enough force to lift water from the roots to the leaves of plants.

thus, cohesion, along with adhesion and surface tension creates a capillary action that keeps water molecules interacting and moving through the plants out to the leaf cells.

therefore, option d) is the correct answer.

explanation:

o conteúdo de calor de um sistema é igual à entalpia apenas para um sistema que é constante

i think its 100.

hope this !
